What the evidence says. Graded moderate: meta-analyses of RCTs show real, modest improvements in glycemic control (HbA1c ~ -0.5%) and lower rates of severe oral mucositis, but many trials are small, short, heterogeneous in propolis source/composition, and several oral-ulcer reviews rate the certainty as very low. (Moderate evidence: Several controlled trials; effects real but modest or context-dependent.)
What is Bee Propolis?
Bee Propolis is a gut and immune supplement used for soothe mouth ulcers (canker sores). NutriDex grades the human evidence as Moderate. Propolis is a resinous mixture honeybees make from plant buds and use to seal their hive; it is rich in flavonoids and phenolic acids with antioxidant, antimicrobial and anti-inflammatory activity. The best human evidence is in type 2 diabetes: pooled RCTs report lower fasting glucose (roughly 13–15 mg/dL) and HbA1c (about 0.4–0.6%), plus modest drops in LDL, CRP and systolic blood pressure. Propolis mouthwash cuts the odds of severe oral mucositis during cancer therapy by about two-thirds, and topical or systemic propolis appears to speed healing and ease pain of recurrent mouth ulcers, though that evidence is rated very low certainty. A standardized oral spray shortened uncomplicated upper-respiratory symptoms in one trial. Effects are real but generally small, and propolis composition varies enormously by geographic source, so results may not transfer between products.

Evidence by outcome
The same supplement can be well-proven for one use and unproven for another — here is the human evidence graded outcome by outcome.
Propolis is generally well tolerated short-term, but it is a notable allergen: contact dermatitis, mouth/lip irritation, swelling and (rarely) anaphylaxis occur, especially in people allergic to bees, pollen, ragweed or chrysanthemum — about 1–7% of patch-tested patients react. Its flavonoids may slow clotting, so use caution with anticoagulants/antiplatelets (warfarin, apixaban, clopidogrel, aspirin) and stop at least two weeks before surgery. It may add to the glucose-lowering effect of antidiabetic drugs — monitor for hypoglycemia. Avoid in pregnancy and limit in breastfeeding due to insufficient safety data. Educational only — always check with your doctor or pharmacist before combining Bee Propolis with any medicine.
Bee Propolis is most often taken for Soothe mouth ulcers (canker sores), Reduce chemo/radiation mouth sores, Lower fasting blood sugar & HbA1c, Ease sore throat / cold symptoms. Bee resin used for mouth ulcers, sore throats and blood-sugar support.

Effects are real but generally small, and propolis composition varies enormously by geographic source, so results may not transfer between products.
What is the typical dose of Bee Propolis?
Oral: 300–500 mg/day standardized extract; topical/mouthwash: alcoholic or aqueous propolis solution applied to the affected area, composition varies widely by source.
Is Bee Propolis safe? Any cautions or side effects?
